Abstract

Existing studies have examined unhealthy food packaging information, mainly focusing on aspects such as the content, color, and text, whilst paying less attention to the boundaries of information. This paper investigates unhealthy foods through three experiments, revealing that the presence (vs. absence) of packaging information boundaries on unhealthy foods has a negative impact on consumers' purchasing intentions (p = 0.040) (Experiment 1). The feeling of constraint mediates this effect (β = −0.078, CI: [−0.1911, −0.0111]) (Experiment 2). Additionally, consumers with an independent self-construal exhibit reduced purchasing intentions when unhealthy food packaging information boundaries are present (vs. absent) (p < 0.001), whereas those with an interdependent self-construal show increased purchasing intentions under the same conditions (p = 0.024) (Experiment 3). This paper reveals the psychological mechanism and boundary conditions of unhealthy food packaging information boundaries affecting consumers' purchasing intention and provides practical inspiration for government policy-making related to unhealthy food packaging.

Abstract

Our aim was to study the morphological and physiological responses of rice to rubbing stimulation. Rice was subjected to rubbing 30 times/day (R30), 60 times/day (R60), 90 times/day (R90) and 0 times/day (control) for 35 days. The height, elongation rates and second internode length were significantly decreased by the three treatments, whereas stem width increased significantly. The tiller number and chlorophyll contents of the top third and top fifth of leaves increased significantly after R30 and R60. In R90, the aboveground biomass was significantly decreased and dead leaf biomass was increased. In R30 and R60, the transpiration rates were 16% and 13% higher than in the control, whereas photosynthetic rates increased 25% and 23%, respectively. Root biomass was significantly increased in R30, and root/aboveground was enhanced in R90. Stomatal conductance and root triphenyltetrazolium chloride-deoxidizing ability was significantly increased by the three treatments. The SOD activities in all treatments and the control were similar after stimulation. POD and CAT activities increased significantly in R30 and R60, and malondialdehyde increased by 42% in R90. Membrane permeability in R30 and R60 decreased 26% and 15%, respectively. The calcium content and soluble protein content increased in R30, whereas the magnesium content decreased. The nitrogen content increased significantly in R30 and R60. The silicon content in the whole plant and the size of stomata increased significantly in the three treatments. Thus, rubbing stimulation had complex effects on rice growth.

Abstract

A “double-locked” and enzyme-activated molecular fluorescent probe for accurate bioimaging and hepatopathy differentiation., Molecular probes activated by a single enzyme have been extensively used in bioimaging and disease diagnosis; however, imaging and identification in an accurate manner remains a challenge for such probes. Here, based on the specificity of enzyme recognition, we engineered a “double-locked” and enzyme-activated molecular probe (NML) for accurate bioimaging and hepatopathy differentiation. Triggered by the successive reactions with leucine aminopeptidase (LAP, first “key”) and monoamine oxidase (MAO, second “key”), the emissive fluorophore (NF) was released. NML can be activated only in the presence of both LAP and MAO and can be silenced when either enzyme is inhibited. Benefiting from the “double-locked” strategy, NML showed higher accuracy for imaging of drug-induced liver injury (DILI) than the “single-locked” probe. With serum testing, NML showed significant differences in mouse models of both CCl4-induced liver cirrhosis and DILI. Significantly, NML can be applied to accurately distinguish serum samples from clinical patients with different hepatopathies. Our smart molecular probe may hold great potential for hepatopathy diagnosis and clinical transformation.

Abstract

A two-photon fluorescent covalent organic framework nanopore is designed for the first time for H2S interference-resistant bioimaging., The complex environment of living organisms significantly challenges the selectivity of classic small-molecule fluorescent probes for bioimaging. Due to their predesigned topological structure and engineered internal pore surface, covalent organic frameworks (COFs) have the ability to filter out coexisting interference components and help to achieve accurate biosensing. Herein, we propose an effective interference-resistant strategy by creating a COF-based hybrid probe that combines the respective advantages of COFs and small-molecule probes. As a proof of concept, a two-photon fluorescent COF nanoprobe, namely TpASH-NPHS, is developed for targeting hydrogen sulfide (H2S) as a model analyte. TpASH-NPHS exhibits limited cytotoxicity, excellent photostability and long-term bioimaging capability. More importantly, compared with the small-molecule probe, TpASH-NPHS achieves accurate detection without the interference from intracellular enzymes. This allows us to monitor the levels of endogenous H2S in a mouse model of cirrhosis.

Abstract

A near-infrared fluorescent probe has been developed for real-time simultaneous visualization of intracellular hypoxia and the subsequent induced mitophagy., Mitophagy induced by hypoxia plays an important role in regulating cellular homeostasis via the removal of dysfunctional mitochondria in the lysosomal degradation pathway, which results in physiological changes in the mitochondria, such as the pH, polarity and viscosity. However, the lack of an effective method for imaging of both the hypoxic microenvironment and the resulting variable mitochondria limits the visualization of hypoxia-induced mitophagy. Based on the specific mitochondrial pH changes during the hypoxia-induced mitophagy process, we have reported a near-infrared fluorescent probe (NIR-HMA) for real-time simultaneous visualization of the hypoxic microenvironment and the subsequent mitophagy process in live cells. NIR-HMA selectively accumulated in the hypoxic mitochondria in the NIR-MAO form, emitting at 710 nm, and then transformed into NIR-MAOH, emitting at 675 nm, in the acidified mitochondria-containing autolysosomes. Importantly, by smartly tethering the hypoxia-responsive group to the hydroxyl group of the NIR-fluorochrome, which shows ratiometric pH changes, NIR-HMA can differentiate between different levels of the hypoxic microenvironment and mitophagy. Furthermore, using NIR-HMA, we could track the complete mitophagy process from the mitochondria to the autolysosomes and visualize mitophagy caused only by hypoxia both in cancer cells and normal cells. Finally, NIR-HMA was applied to investigate the role that mitophagy plays in the hypoxic microenvironment via the cycling hypoxia-reoxygenation model. We observed a decreased fluorescence ratio after reoxygenation and a further increased mitophagy level after hypoxia was induced again, suggesting that mitophagy might be a self-protective process that allows cells to adapt to hypoxia. Our work may provide an attractive way for real-time visualization of relevant physiological processes in hypoxic microenvironments.

Abstract

Mutations in mitochondrial DNA (mtDNA) are important causes for type 2 diabetes mellitus (T2DM). To investigate the association between mtDNA mutations/variants and diabetes, we reported here clinical, genetic and biochemical characterization of a Chinese pedigree with maternally transmitted T2DM. Using PCR and direct sequencing analysis of mitochondrial genomes from the matrilineal relatives, we identified two potential pathogenic mutations, m.T4216C (p.Y304H) and m.C5178A (p.L237M) in the ND1 and ND2 genes, respectively, together with a set of genetic polymorphisms belonging to the human mitochondrial haplogroup D4b. Moreover, by isolating and analyzing polymononuclear leukocytes generated from the T2DM patients and controls, we identified lower levels of mitochondrial membrane potential and ATP production in T2DM patients than in the controls, in contrast, a significantly higher level of reactive oxygen species was observed in the T2DM patients carrying both of the m.T4216C and m.C5178A mutations (p < 0.05 for all). In addition, the plasma levels of malondialdehyde and 8-hydroxydeoxyguanosine in the T2DM patients markedly increased, while the level of superoxide dismutase decreased (p < 0.05 for all). Taken together, our data indicated that the ND1 T4216C and ND2 C5178A mutations may lead to oxidative stress and impair the mitochondrial function, and this, in turn, might have been involved in the pathogenesis and progression of T2DM in this pedigree. Thus, our study provides novel insight into the pathophysiology of T2DM that is manifested by mitochondrial dysfunction. [ABSTRACT FROM AUTHOR]
